The requirements contained in 49 CFR 192.353, which is adopted by reference in R 460.20606, are superseded by all of the following provisions: (a) An operator shall install a customer's meter and regulator outside the building, unless any of the following apply: (i) The distribution system operates at 10 psig or less and an outside meter set assembly is not practical. (ii) The building is a commercial building, industrial building, or apartment building and an outside meter set assembly is not practical. (iii) The building is a row-type house or house where the proximity of adjoining buildings makes outside meter set assemblies impractical. (b) A service line excluded under subdivision (a) of this rule must include an outside above grade riser, if practical. (c) If an outside meter set assembly or an outside above grade riser is installed, then the above grade piping must be designed to prevent an external force applied to the service line from being transferred to and damaging the inside piping. (d) An operator shall install a meter and service regulator, whether inside or outside of a building, in a readily accessible location and shall protect the meter and regulator from corrosion and other damage, including but not limited to, vehicular damage if installed outside a building. An operator shall not install a meter in a bedroom, closet, bathroom, under a combustible stairway, or in an unventilated or inaccessible place. (e) An operator shall ensure that a service regulator installed inside a building is located as near as practical to the point of service line entrance. (f) An operator shall ensure that a meter installed inside a building is located in a ventilated place not less than 3 feet from a source of ignition or heat that might damage the meter. (g) An operator shall ensure that the upstream regulator in a series is located outside of a building unless it is located in a separate metering or regulating building.
